Answer 1

It works at ICS4.0.3 ,Moto XT910,FFmpeg 0.7

I use extradata for store MediaFileName,then get metadata from codes:

DataSource::RegisterDefaultSniffers();
sp source ;
source = createSource((char*)MeidaFileName);
if(source==NULL){
    return -1 ;
}
meta = source->getFormat();
if(!meta->findData(kKeyAVCC, &type, &data, &data_size))
{
    return -1 ;
}
meta->setCString(kKeyMIMEType, MEDIA_MIMETYPE_VIDEO_AVC);

then you can OMX::create(there are some difference for Android 2.3 and ICS)
